ABSTRACT
Eosinophilic cholecystitis is a rare form of cholecystitis that is clinically indistinguishable from the predominant form of calculous cholecystitis. Histologically, it is characterized by a dense, transmural leukocyte infiltrate composed of more than 90% eosinophils. A 60-year-old woman complained of right upper quadrant pain. She had no allergic or medicine history. An abdominal CT scan revealed thickened gallbladder wall but no cholelithiasis, and a cholecystectomy was performed. Histologic examination showed transmural eosinophilic infiltration of the gallbladder wall.

Dieulafoy's lesion is a rare cause of repetitive and massive gastrointestinal bleeding, and this is characterized by an isolated arteriole protruding through a small mucosal defect. Dieulafoy's lesion is generally found in the stomach within 6 cm of the gastroesophageal junction, and usually on the lesser curvature, but many lesions have been reported in extragastric locations, including the esophagus, small bowel and rectum. A Dieulafoy's lesion in the ampulla of Vater is extremely rare, and only one such case has been reported in the Korean population. We experienced a rare case of Dieulafoy's lesion in the ampulla of Vater with massive pulsatile bleeding, and this was successfully treated by transparent cap-assisted endoscopic hemoclipping. We report here on this case with a review of the relevant literature.
